<h2>Slowness on SOW list and record page due to custom UI scripts</h2><br/><div style="overflow-x:auto"><div> <div> <div> <div>The ServiceNow platform offers configurable workspaces, such as the Service Operations Workspace (SOW), which often requires making GraphQL calls when loading a list or record. These calls fetch metadata, including the sys_ui_script. Some users have reported slowness issues, including browser tab crashes with out of memory errors, which were caused by custom sys_ui_script records that were too large, particularly third-party libraries.</div> <div> </div> <div>When the number of sys_ui_script records is high or their content size is large, it takes more time to parse the JavaScript on the client-side, leading to slowness and out of memory errors. To avoid such issues, customers are advised to review their custom sys_ui_script records with the UI type set to 'ALL' or 'Mobile/Service portal' and set the 'ignore_in_now_experience' flag to 'true' to prevent them from being loaded and parsed into workspaces.</div> </div> </div> </div></div>
